Which Steel Strip Is Best for Roller Shutter Door Springs?
Roller shutter doors rely heavily on their spring systems to operate safely and smoothly. Whether used in commercial warehouses, garages, or industrial loading bays, the spring is responsible for counterbalancing the door’s weight — allowing it to open and close effortlessly. Because these springs experience constant torsion, cycling, and stress, selecting the right steel strip […]
C75S High Carbon Steel Strip — The Classic Choice for Springs and Saw Blades
1. Overview C75S belongs to the family of high carbon spring steels (C67S, C70S, C75S, C80, C85S, C95S), widely recognized for its excellent hardness, tensile strength, and elasticity after proper heat treatment.Jiaxiao MTC manufactures C75S high carbon steel strips in both cold-rolled annealed and hardened and tempered conditions, ensuring high precision in thickness, width, and […]
How Heat Treatment Improves Elasticity in Steel Strips
In steel strip production, elasticity is one of the most important mechanical properties — especially for applications like springs, blades, and flexible components. Elasticity determines how well a steel strip can return to its original shape after deformation. The key to controlling elasticity lies in heat treatment, a precise process that transforms the steel’s internal […]
What is Annealed Steel Strip?
When choosing steel materials for manufacturing, many engineers and buyers come across the term “annealed steel strip.” But what exactly does it mean, and why is it widely used in industries such as automotive, tools, and shoe manufacturing? Let’s explore. 1. The Annealing Process Annealing is a heat treatment process designed to alter the physical […]
The Difference Between Cold Rolled and Hot Rolled Steel Strip
When it comes to steel strip, one of the most common questions is: what’s the difference between cold rolled and hot rolled? Although both belong to the flat steel product family, the production process, surface quality, and applications make them very different. 1. Production Process ? In short: hot rolling focuses on formability, while cold […]
Hardened and Tempered Steel Strips for Springs and Blades
Hardened and tempered steel strips are essential materials in industries that demand high strength, durability, and flexibility. Produced through a precise quenching and tempering process, these strips combine hardness with toughness, making them ideal for springs, saw blades, knives, and construction tools. What Are Hardened and Tempered Steel Strips? The hardening process involves heating steel […]
Why More Manufacturers Are Switching to Quenched & Tempered Steel Strip
Introduction In today’s high-precision and high-performance industries, material reliability is everything. From spring manufacturers to blade producers, companies are facing increasing demands for strength, durability, and consistency. As a result, more manufacturers are turning to quenched and tempered (Q&T) steel strip—a material that meets modern engineering standards with superior mechanical properties. 1. What is Quenched […]
